A car seat has a base for placement on a vehicle seat and a seat shell attachable to and detachable from the base. A latch mechanism is biased to a latched arrangement attaching the shell to the base. A release actuator is connected to the latch mechanism and can move the latch mechanism to a released arrangement, detaching the shell from the base permitting its removal from the base. The shell can be optionally adjustable on the base between at least two different recline positions. The latch mechanism in the latched arrangement can then also retain the shell in one of the recline positions. A recline actuator can be connected to the latch mechanism and can move the latch mechanism allowing adjustment of the shell recline position but not permitting removal from the base.
